Yes, but inexpertly, I am sure. The only thing that I'm able to pin down
is that there's a conversation going on between the two (db & web) for
that whole time. It goes something like this:

17:35:10.993291 > istanbul.43712 > odin.wildbrain.com.4140: P
472345083:47234508

(DF)
17:35:10.993291 < odin.wildbrain.com.4140 > istanbul.43712: . 1:1(0) ack
3 win 1

17:35:10.993291 < odin.wildbrain.com.4140 > istanbul.43712: P 1:4(3) ack

...and continues for about 5 seconds/~300 packets, after which I get
content. Unfortunately, that doesn't tell me much. Interestingly,
though, it's absolutely repeatable; if I hit "back" and "forward" in my
browser, the same pause happens.

I'm going to turn on debugging (tomorrow) and see if I get any time
related information to help me along.

Thanks!
